Ready Stack -- How Come?
For new people who come on board here at Dell Technologies, the learning curve can be steep. We provide hardware and software infrastructure solutions of all shapes and sizes to meet customer demands. The product portfolio is deep and wide.
As technologically minded consumers in this era, when confronted by a seemingly overwhelming number of choices, we often rightfully ask the subject matter expert: "What would you recommend?"
This is exactly the question that the Ready Stack program seeks to answer for our customers who are looking for powerful and reliable converged infrastructure solutions. Not a "product" as such, Ready Stack provides documents that describe reference architectures that we feel work well together. We write and post these documents on the Dell Technologies Info Hub on a regular basis. Many of these reference architectures provide detailed deployment instructions, in the form of a deployment guide; all reference architectures include a detailed design guide.
The entire collection is complemented by a Reference Architecture Guide that lists the Dell EMC compute, storage, and network portfolios that we draw upon when we put together a design. The entire portfolio is composed of Dell Technologies products, backed by single call support.
Simply put, Ready Stack enables you to build your own converged infrastructure solution using your choice of Dell EMC best-in-class technology components. Each reference architecture provides a flexible combination of compute (such as MX7000 blade servers or rack servers), storage (such as PowerStore, PowerMax, or Unity XT), and networking (including S Series ToR switches and Z Series core switches). In the end, it is the customer who decides which combinations of these assets best meet their requirements.
Our Ready Stack docs sometimes offer early glimpses into the latest products that are available from Dell Technologies. So we encourage you to check back on the Ready Stack library from time to time to take advantage of an ever widening selection of compute, network, storage, and data protection options!

Looking Ahead: Dell Container Storage Modules 1.2
Mon, 21 Mar 2022 14:31:56 -0000
|Read Time: 0 minutes
The quarterly update for Dell CSI Drivers & Dell Container Storage Modules (CSM) is here! Here’s what we’re planning.
CSM Features
New CSM Operator!
Dell Container Storage Modules (CSM) add data services and features that are not in the scope of the CSI specification today. The new CSM Operator simplifies the deployment of CSMs. With an ever-growing ecosystem and added features, deploying a driver and its affiliated modules need to be carefully studied before beginning the deployment.
The new CSM Operator:
- Serves as a one-stop-shop for deploying all Dell CSI driver and Container Storage Modules
- Simplifies the install and upgrade operations
- Leverages the Operator framework to give a clear status of the deployment of the resources
- Is certified by Red Hat OpenShift
In the short/middle term, the CSM Operator will deprecate the experimental CSM Installer.
Replication support with PowerScale
For disaster recovery protection, PowerScale implements data replication between appliances by means of the the SyncIQ feature. SyncIQ replicates the data between two sites, where one is read-write while the other is read-only, similar to Dell storage backends with async or sync replication.
The role of the CSM replication module and underlying CSI driver is to provision the volume within Kubernetes clusters and prepare the export configurations, quotas, and so on.
CSM Replication for PowerScale has been designed and implemented in such a way that it won’t collide with your existing Superna Eyeglass DR utility.
A live-action demo will be posted in the coming weeks on our VP YouTube channel: https://www.youtube.com/user/itzikreich/.
CSI features
Across the portfolio
In this release, each CSI driver:
- Supports OpenShift 4.9
- Supports Kubernetes 1.23
- Supports the CSI Spec 1.5
- Updates the latest UBI-minimal image
- Supports fsGroupPolicy
fsGroupPolicy support
Kubernetes v1.19 introduced the fsGroupPolicy to give more control to the CSI driver over the permission sets in the securityContext.
There are three possible options:
- None -- which means that the fsGroup directive from the securityContext will be ignored
- File -- which means that the fsGroup directive will be applied on the volume. This is the default setting for NAS systems such as PowerScale or Unity-File.
- ReadWriteOnceWithFSType -- which means that the fsGroup directive will be applied on the volume if it has fsType defined and is ReadWriteOnce. This is the default setting for block systems such as PowerMax and PowerStore-Block.
In all cases, Dell CSI drivers let kubelet perform the change ownership operations and do not do it at the driver level.
Standalone Helm install
Drivers for PowerFlex and Unity can now be installed with the help of the install scripts we provide under the dell-csi-installer directory.
A standalone Helm chart helps to easily integrate the driver installation with the agent for Continuous Deployment like Flux or Argo CD.
Note: To ensure that you install the driver on a supported Kubernetes version, the Helm charts take advantage of the kubeVersion field. Some Kubernetes distributions use labels in kubectl version (such as v1.21.3-mirantis-1 and v1.20.7-eks-1-20-7) that require manual editing.
Volume Health Monitoring support
Drivers for PowerFlex and Unity implement Volume Health Monitoring.
This feature is currently in alpha in Kubernetes (in Q1-2022), and is disabled with a default installation.
Once enabled, the drivers will expose the standard storage metrics, such as capacity usage and inode usage through the Kubernetes /metrics endpoint. The metrics will flow natively in popular dashboards like the ones built-in OpenShift Monitoring:
Pave the way for full open source!
All Dell drivers and dependencies like gopowerstore, gobrick, and more are now on Github and will be fully open-sourced. The umbrella project is and remains https://github.com/dell/csm, from which you can open tickets and see the roadmap.
Google Anthos 1.9
The Dell partnership with Google continues, and the latest CSI drivers for PowerScale and PowerStore support Anthos v1.9.
NFSv4 POSIX and ACL support
Both CSI PowerScale and PowerStore now allow setting the default permissions for the newly created volume. To do this, you can use POSIX octal notation or ACL.
- In PowerScale, you can use plain ACL or built-in values such as private_read, private, public_read, public_read_write, public or custom ones;
- In PowerStore, you can use the custom ones such as A::OWNER@:RWX, A::GROUP@:RWX, and A::OWNER@:rxtncy.
